Prompt Menus
You can use a main menu and submenus of prompts to direct callers to
individuals and services in your organization. You configure prompt
menus for each Auto Attendant by using the Menu Tree dialog box. The
Menu Tree dialog box consists of 13 button rows that you use to assign
actions to the key pad buttons (see"Auto Attendant Buttons" on
page 317). Be sure to define the menu time-out behavior so that if a
caller does not respond to the Auto Attendant prompts (for example, a
caller using a rotary telephone) the system automatically routes the call to
a time-out destination.
CAUTION: To ensure that forwarded calls eventually reach a valid
destination, you must configure a time-out action for each Auto
Attendant menu tree. For example, if the time-out action for the Auto
Attendant menu tree is set to Disabled, and Maximum number of prompt
repeats is set to 1, the system disconnects a call forwarded to the Auto
Attendant because the forwarding party always hears a portion of the
Auto Attendant prompt. Likewise, if the time-out action for the Auto
Attendant Menu Tree is set to Disabled, and Maximum number of prompt
repeats is set to 2 or 3, the system disconnects the forwarded call if the
forwarding party stays on the line long enough to hear at least a portion
of the final repeated prompt.
Main Menus The main menu prompt follows the time-dependent
greeting if you have one enabled. The main menu prompt should
describe all Auto Attendant options and can be up to five minutes long.
The default Auto Attendant main menu prompt says:
"If you know the extension of the party you want to reach, you may enter
it at any time. To reach the name directory, press 9. To reach the Auto
Attendant, press 0 or remain on the line. Thank you for calling."
